NEMESIO VICENTE, OF CARTAGENA, SPAIN.

WATER-TUBE BOILER.

SPECIFICATION forming part of Letters Patent No. 706,787, dated August12, 1902.

Application filed February 12, 1902. Serial No. 93,659. (No model.)

' subject of the King of Spain, and a resident of Oalle de Medieras 9,Oartagena, Spain, have invented certain new and usefulImprovementsinWater-TubeBoilers,(forwhich I have made application forpatent in Great Britain under No. 1,200 and dated the 16th of January,1902,) of which the following is a specification.

This invention relates to water-tube boilers mainly consisting of anumber of similar elements, each element broadly consisting of adownwardly-extending lower tube closed at its base and opening out atits upper part into a larger chamber. From the upper part of thischamber there proceeds a steam-conducting or take-off tube, while awater-feed tube enters the chamber at the lower part and extends downthe lower tube, into which it supplies the feed-water. All thesteam-takeoff tubes of a number of these elements communicate with theupper part of a main drum or reservoir, while all the watersupply tubesof those elements communicate with the lower part of the main drum, fromwhich the supply of fluid to each element is so conducted, while thesteam is delivered from each element to the upper part of the main drum;and the invention has reference to the constructions and combinations ofparts, all as hereinafter described and claimed.

The invention is now further described with reference to theaccompanying drawings, whereon- Figure 1 is a vertical section (aportion being broken away) of a single element such as before referredto, being a diagrammatic View merely illustrative of the principles ofthe construction. Fig. 2 shows in vertical section and plan a group ofsuch elements. Fig. 3 is a vertical section showing the generalarrangement of a water-tube boiler composed of a number of theseelements, where they are arranged with the lower tubular parts in aninclined position. Fig. 4 is a vertical sectional front elevation. Fig.5 is a sectional side elevation, and Fig. 6 is a sectional plan viewwhere the elements are arranged in vertical position. Fig. 7 is avertical section of a portion of one of my boilers drawn to a largerscale than the previous figures chamber.

and showing the upper parts of the elements with their connections tothe main drum. Fig. 8 is a plan View of Fig. 7. Fig. 9 is an elevation,and Fig. 10 is a section, of the upper ends or chambers of several ofthe elements, showing the connection of the steam take-off and supplytubes, where one of each is provided for each element. Fig. 11 is avertical section of the upper portion or chamber of one of theelements,showing means for removing the fluid-supply tube from withinsame; and Fig. 12 is a vertical cross-section of Fig. 11. Fig. 13 is aplan with the cover removed. Fig. 14 is a section on the line X Y, andFig. 15 is a section on the line X Y, all of Fig. 11. Fig. 16 is anelevation of the chamber portion of a series of elements; and Fig. 17 isa vertical section of the same, illustrating an application where thechambers have a single steam take-off common to all and a separatefluid-supply tube for each Fig. 18 is an elevation. Fig. 19 is avertical section, and Fig. 20 is a trans verse section showing anarrangement where a series of chambers have a single steam-take oif tubeand a single water-supply tube common to all.

In its elementary form and as shown by the diagram Fig. 1 each elementconsists of what I will call the lower tube 1, of any suitable lengthand which is so arranged in relation to the furnace, as hereinafterexemplified, that the heated gases of the furnace act upon the exteriorof the tube. The tube 1 is arranged in either a vertical position orsomewhat inclined and is closed at its lower end, while its upper end isformed with or connected to a chamber 2, which is of greater diameterthan the tube 1. Connected to the upper part of the chamber (notnecessarily the top, as at Fig. 1) is a take-off tube 3 for the steam,while water is supplied to the element by a tube 4, which enters thechamber at a point below the take-off tube 3 and extends down the tube1, being open near the closed end of same, so that water is suppliedinto the lower end of the tube 1 and steam is taken off at or near theupper part of the chamber 2, and thus an effective circulation isestablished independently in each element, while each element is capableof such construction, as will hereinafter be explained, as

are caused to circulate between the lower tubes 1. Obviously theelements may be so arranged that the lower tubes can be either in aninclined position or in a vertical position, and at Fig. 3 I have showna sectional diagram, where the lower tubes 1 of the elements arearranged in an inclined position, i

so that the gases from the furnace 5 pass between the said tubes. Thewater-feed tubes 4 of each element communicate with the lower part ofthe main drum 6, Fig. 3, while the steam-take-oif tubes 3 communicatewith the upper part of the said drum 6, and the said tubes 3 4 and thechambers 2 may be included in a casing, such as 7.

8 is a drum for collecting the mud, and 9 is the chimney from thefurnace.

Figs. 4, 5, and 6, as previously stated, are diagrams showing theelements arranged vertically, and being figured to correspond with Figs.1 to 3 will be readily understood without further description.

It is usually necessary and advantageous in the practical constructionof the boiler to arrange that the interior of each chamber 2 can beconvenientlyinspected and also to enable the tubes supplying theelements to be removed without necessarily removing either the lowertubes 1 or the chambers 2, which parts are of course supported by asuitable framework of the boiler. At Figs. 7 and 8 there is shown aconstruction by which these objects can be effected, and it will beobserved by reference to these figures that the upper end of eachchamber 2 is provided with a removable cover 10, and there is alsofitted in the interior a movable part 11, adapted to be slid intoposition in the interior of the chamber 2 or removed therefrom after thecover 10 has been taken away. This removable part- 11 is formed so as tocomprise within itself the downwardly-extending portion of the waterfeedtube 4in the extreme right-handelement of Fig. 7, while since in theconstruction here shown the tubes of that right-hand element passthrough the left-hand element the slide part 11 of such left-handelement comprises not onlya continuation of the water-feed tube 4 ofthat element, but also a portion of the water-feed tube of theright-hand element and a portion of the steam-take-off tube of theright-hand element. The slide part 11 need not be made to veryaccurately fit the interior of the chamber 2, because the object of theconducting-tubes is only to give direction to the circulation. As I havenow shown, the steam-conducting tubes to the drum 6 and the water-feedtubes from that drum in passing to their respective elements may eitherall pass through the interiors of series of elements or may separately.

At Figs. 9 and 10 is shown an example where each element has its ownseparate water-feed tube 4 and its own separate steamtake ofi tube 3,and all these tubes pass through the chamber2 of the first element of aseries, one of the water-feed tubes and one of the steam-take-oif tubescommunicating with that first element, while the remaining steam andwater tubes pass on to the next element, with which two communicate, theremaining tubes passing to the next element, and so on.

I have explained with reference to Figs. 7 and8 that the interior of thechamber 2 is provided with a movable part 11, and this movable part whenin position provides within itself continuation-passages of the tubesfrom one side of the chamber to another and also carries a portion ofthe water-feed tube 4 belonging tov its own particular element. In orderthat this arrangement may be more clearly understood, I have furtherillustrated the same, upon a larger scale than the previous figures, atFigs. 11 to 15, inclusive, where the removable cover 10 of the chamber 2is clearly shown, and when this cover 10 is taken away the part 11 canbe withdrawn from within the chamber 2, bringing with it portions of thesteam and water tubes 3 4. In

pass to each element the instance shown the part 11 brings away' with itthe portions of two of the steam-tubes 3 3 and two of the water-tubes 44, which pass through the chamber 2 on their way to the next series ofelements, and it also brings away with it the continuation of the lowerwater-tube 4, which supplies that element shown in the figures.

The part 11, as shown in Fig. 12, is made of a somewhat taperingformation and is so fitted within the casing of the chamber 2 that itcan be readily slid out. Obviously the steam-tube serving thisparticular chamber 2 has no connection with the part 11, but merelyopens into the upper part of the said chamber 2.

With the elements hitherto dealt with each chamber 2 has been fittedwith its own particular steam and water tubes 3 4; but at Figs. 16 and17 I have shown a construction where a series of chambers 2 are servedby one common steam-take-off tube 3, while the water is supplied to eachelement by separate supply-tubes 4 4 4, &c. The result of thisarrangement is that the steam-tube 3 communicates with the first chamber2, and the first chamber 2 is then connected with the upper part of thenext chamber 2 by a tube 3, and so on.

In Figs. 18, 19, and 20 I have shown a similar arrangement, but wherethe water-supply is effected by a water-supply tube 4 common to a seriesof elements and a steam takeoff is also effected by a steam-tube 3, alsocommon to the same series of elements, and the construction will bereadily understood by an inspection of these figures, where it will beseen that the movable part 11 carries a kind of T-shaped tube, the upperarms of the T when in position forming the bridging or continuationparts of the main watertube, while the downward extension of the T-piececomposes the water-supply tube leading to near the base of the lowertube 1 of the element.

WhatI claim as my invention, and desire to secure by Letters Patent, is

1. In water-tube steam-boilers, the combination with a drum and a numberof uniform elements each consisting of a downwardlyextending lower tubeclosed at its base, a chamber with which the upper end of the lower tubecommunicates, and a removable cover to the said chamber; of a removableslide for each chamber adapted to be slid into same, and guides in thechambers to receive the slides, water-supply tubes extending from thelower part of the drum equal in number to the elements employed, andsteamtubes extending from the upper part of the drum also equal innumber to the elements employed, all the tubes from the drum enteringthe wall of the chamber of the first element, the slide of the firstchamber being formed with steam and waterconducting passages coincidingwith continuation-tubes to the next element-chamber, and also carryingthe downwardly-extending water-feed tube of its own chamber, theremovable slide of the second chamber carrying the water-supply tubetherefor and communicating passages for the next chamber and so on, afurnace, and means for supporting the elements in position so that thefurnace-gases pass between the lower tubes of the elements,substantially as set forth.
